Q.6 Energy and Power Signal (Continuous):
A measure of signal length is determined by following two important quantities of a signal.
a) Energy Signal:
A signal x(t) is said to be energy signal if and only if the total normalized energy is finite and non-zero. Non-periodic signals are energy signals. Total energy of a signal x(t ) can be expressed as:
b) Power Signal:
The signal x(t) is said to be power signal, if and only if the normalized average power p is finite and non-zero. Practical periodic signals are power signals. Total power of a signal x(t) is given by :
Write a MATLAB code to find the energy and power of the following signals and comment about results. (HINT: You must make use of symbolic toolbox with int() and limit() built-in functions. )
